ligotools_listto get a list of LIGOtools packages which have been installed on the system. (If this doesn't work, see the FAQ entitled "What do I need to do to use LIGOtools?".) The output should look something like this:
LIGOTOOLS is /ligoapps/ligotools Package Active Other versions --------- -------- ---------------- Fr v4r31b v4r31a, v4r31, v4r11 dataflow 2.2.2 2.2, 2.1, 2.0, 1.4 dataviewer 3.5 3.4, 3.3 dtt 1.0 fftw 2.1.3 guild 3.7.0 3.4.3, 3.3 lal 0.8 0.7, 0.6, 0.5 ltadmin 1.4 1.3, 1.2, 1.1, 1.0 mininds 3.2 3.1 root 2.25.03 tclexe 8.3.2a 8.3.2 wat 1.62The "active" version is the one which is currently set up for use - that is, its binaries are in $LIGOTOOLS/bin, its libraries (if any) are in $LIGOTOOLS/lib, etc. The "other" versions (generally, older versions) are still present on disk (in $LIGOTOOLS/packages) but are not usable through normal means. The person who set up LIGOtools may change the active version using the ligotools_activate utility.
